There's a feature in TRAMP to do just that. This used to be called
"multi-hop" but now is configured with `tramp-default-proxies-alist';
the documentation is still under (info "(tramp) Multi-hops"). Here's
what I have in my .emacs to use it:

  (setq tramp-default-method "ssh")

  (eval-after-load "tramp"
    '(when (boundp 'tramp-default-proxies-alist)
           (add-to-list 'tramp-default-proxies-alist
                  '("\\`\\(.*\\.example\\.com\\|somehost\\.example\\.org\\)\\'"
                    "\\`root\\'"
                    "/ssh:%h:"))))

I set things like port and username In my .ssh/config:

  Host *.example.com
    User foo

  Host somehost.example.org
    User bar
    Port 666

Now I can do C-x C-f /sudo:www.example.com:/ <RET> and work on the
remote host as root. 

HTH,
